ABSTRACT:
A method employing a reciprocating feed of a band saw to an abrasive wheel and a pitch feed of the saw to the abrasive wheel. The saw is positioned so that during a part of the pitch feed the portion of the tooth back edge adjacent to the tooth tip comes into contact with one shaped surface of a supporting element, whereby the saw is retarded and at the same time the portion of the tooth edge is strengthened and planished. During the remaining part of the pitch feed the portion of the tooth front edge adjacent to the tooth tip makes contact with the other shaped surface of the supporting element, whereby the portion of the tooth front edge is strengthened and planished. In the machine for carrying this method into effect the supporting element located after the abrasive wheel, as viewed in the direction of the pitch feed, has two shaped surfaces disposed in relation to each other so as to form a wedge.
